Abstract

Abdillah,Bagas Husni.2025.” Design model and Implementation of an Automated Blockage Detection System on Sea water pump Pipelines with Backup Pump Activation Based on Sensors and Microcontrollers on LNG Vessel ENERGY ADVANCE” The cooling system on a ship is an important element to maintain engine performance and prevent overheating. One of the main components is the seawater pump which often faces obstacles in the form of blockages due to the accumulation of dirt and marine biota. This study aims to design and implement an automatic system based on sensors and microcontrollers to detect blockages in the seawater pump channel in real-time and automatically activate the pump backup to ensure the smooth operation of the lighting system. Deadlocks due to marine biota occur due to ships entering the border area between Russia and Japan which have different temperature differences, Japan has a warmer sea air temperature in the Russian band, so many fish expand into Japanese waters in search of air that has a warm temperature, this results in many fish being sucked into the sea channel and clogging the seawater pump filter. So that the design of a pump automation system and deadlock detection was made using an ESP32 microcontroller, a YF-S401 flow sensor, and a relay module as an actuator. The test results showed that the system successfully detected flow disturbances and automatically activated the pump backup when a deadlock occurred, with a practicality level reaching 90% based on user validation. This research contributes to the development of more efficient and reliable automatic cooling systems in the maritime world.
